When you work correct, you should be done with Phase 1 at 31th december 09

Well Norman, I think I might have done something that is not correct. For the last 30 test, I seem to move forward several test and primo would go back track several test and move forward some more. Or worse one test would move forward but two run would come up with different bits. I normally took the lowest bit but eventually it would back track or become dead end and primo would back track until it can find another track to move forward. Last night I only ran 1 core on test 376 run1, this morning it was on test 378 and has backtracked again to test 377 with the same bit number.

Is this normal. Happy new year to you already.

Pity Engracio !
Maybe, you don't have the same strategy in detail. (Or I misunderstand you) I believe , you have now 18500 bits ( a tiny number

)

My number is out of any power laws ( for running times ).
At this time I have any TEST of 28 and 29. (37476 bits)

Also happy new year to you ! Only 3.5 hours than we have 2010

P.S. I have now a Phenom II X4 965 (3.4 GHz). 10^700+7 takes 2min 40s

I have no doubt that your calculation is correct, it is just that I seem to be going back and forth on the test. It would go forward a few test then back track one or two test. Redoing the same test seems to take longer. That is why I have not made more progress in the last two weeks. Good thing is I have almost done 250 test on Phase two.

Norman I have finally finished 2^26827+77783 and running the verification on it.

After 24hrs it is on test 360/1076. w00t

I know that after test 675 Primo was just crunching right thru it, on both phase 1 and phase 2. What should I expect when Primo complete the verification? Thanks.

Congratulations, Engracio. You should be finished within another day. I'll update post #1. I see that the prime is just barely too small to make Chris Caldwell's top 20 ECPP list, but we should send the certificate to Marcel Martin, as it is still one of the largest numbers ever to be certified by PRIMO.

Congrats Engracio! A great effort!

engracio · 2010-01-19, 02:59

Thanks guys, Primo verified the prime as proven in 33hrs. Phil pls check your email to see if we need anything else.

Cybertronic · 2010-01-19, 07:44
